Just because I see alot of people miss-labling their deer.

Here's the way it goes:

"For most deer the male is called a buck and the female is a doe, according to the size of the species. For many medium-sized deer the male is a stag and the female a hind, while for many larger deer the same words are used as for cattle: bull and cow. Terms for young deer vary similarly, with that of most being called a fawn and that of the larger species calf; young of the smallest kinds may be a kid. A group of deer of any kind is a herd. Usage of all these terms may also vary according to dialect. The adjective of relation pertaining to deer is cervine; like the family name "Cervidae" this is from Latin cervus, "deer."

The word 'hart' is an old alternative word for "stag", especially in a (British) Medieval hunting context."

So yes.
If your deer is a whitetail or a deer of similar size, also including many smaller deer, it's either a doe, a buck, or a fawn.

If your deer is slightly larger, fitting into the 'medium' size catagory, it is a stag, hind, or a fawn.

If your deer is HUGEEE, like a moose, it is either a bull, a cow, or a calf.

OKAY? <3
